To (ZZZ '20]: om 2 15' may; concern lo itlmown that l, TILLIAM C. Vim: DRESSER, a citizen of the lnit-ed States 0t America, residing: at lletroit, in the county ot Wayne and State of lvliehignn, have invented certain new and iiseiiil improvement. in Bushings, of which the following is nspecitlootion, reference being haul there in. to the accompanying drawings.

My invention relates to bushings for conentric shafts, and more particularly to that type of bushing which forms both a spacer and a hearing.

invention resides in the provision of a simple and ellieient rleviee which may be easily and cheaply manufactured; in the forming of o. hearing portion resilient so as to automatically take up Wear, and permit the hearing to be engages with shafts of slightly varying diameters; and further in oerteii'i novel construct-ions and arrangements of parts. i

in the drawings, Figure 1 is a longitudinal, central section through s. pair of coneontricslly arranged shafts having my im proved hushiilg applied thereto; Fig. 2 is a longitudinal section through the spacer; mg. 3 is a section out-he line ar-s-m of Fig. l Fig. 4 is eperspeotive view of the blank from which if especial is formed; Fig. 5-.is :1. similar View of the finished esticle; and Fl llillusti'etes a modification; Fig. 7 is e longitudinal sectional View through Fig. 4. Fig. 8 is e transverse seetionel view of Fig. 5.

A clesignstes the hollow 'o'iieer shaft and B the inner concentric shaft, the former be ing herein shown as the outer sleeve of a steering stem, and the letter as ehe rotatable controlled member that, is fixedly secured to the steering Wheel '0.

My improved bushing is made of metal, prefemhlystoel mill has hearing portions E {incl F ti'iltly noting the inner shaft but pernii ting the latter to turn therein. end; is annular spacing rings l and J and into rel connecting iiortions G and H, the connecting poi-lions being arranged as shown at, suhsumeinlly clizinieti'ienl points. The bearing portions E and F have their rings I and J and their ends integral with the connecting-portions Sr and. l.

The bushing is nestle from a tubular blank K (see Fig. 5; slitted at, spaced points i..- M on each side, the slits extending only neat-nag portions (2 ll.

part way around. the blank leaving the con The blank is then engaged with suitable dies to force inward. the portion ot the metal intermediate the slits. flanges N (l at opposite side edges of the segments which merge into the connecting; portions. The l'nl'tc therefore, carry the segments and with the parts H 1 form elinn eel-shaped connections between the adjacent 65 ends of the opposed homing segments. Such a struotuee not only is easily end cheaply manufactured, since ii: may be readily formed from a tubnlnnblank, but also the manner "j'the opposetl segments of the "Hi of eonnect n bearing, give them e. certain degree of resiliency suflicient to take up wear occurring he tween the loseri g and the rotatable shaft.

This resiliency also permits a. slight verie tion in the diameter of the inner shaft, 78

thereby avoiding the necessity of mnohining the inner shaft toe. highly accurate given diameter.

In the modification snown in Fig. 6 the bearing is pi'oviilecl with lining pistes l? of {so configuration emnpleinen'ery to the hearing segments and secured thereto as by means of pins Q on the lining plates engaging spar tunes R in the segments. Thus, if the lining plates become worn they may be readily reso moved or replaced by new ones.

What I claim as my invention iszl. A bushing min mising annular spacing sections cthnposed of separated spacing rings, a resilient hearing composed of op- 99 posed segmental portions having their ends free from ilhe spocing sections, and a coin neetionbetween the spacing sections anti the sides of the segmental hearings, saitl parts. being formed ot av single piece-of metal.
